how to specifically add data to each item in array in php

Question

basically, I need to output a list of emails in a very specific way for the SendGrid API to understand. it looks like this.

{email:recipient1@example.com},
{email:recipient2@example.com},
{email:recipient3@example.com}

in essence, I need to just add the curly brackets and email: ,

I have no idea how to do this.

my code is this.

$e= array("recipient1@example.com", "recipient2@example.com", "recipient3@example.com");
foreach ($e as $x) {
   echo"{email:$x}, <br>";
}

I'm using echo because when I try to convert it into a var it either gives me an error code or just displays the last email in the $e array.

why is it SO DAMN hard to just add some stuff to each item in an array?

Answer 1

This works on my end...

$e= array("recipient1@example.com", "recipient2@example.com", "recipient3@example.com");
foreach ($e as $x) {
    $y[] = "{email:$x}";
}
$list = implode(",<br>", $y);
//print_r($list);
